The add-on allows CPI to begin production of additional outer wing panel kits used in manufacturing of complete wings for the E-2D Advanced Hawkeye, an all-weather, tactical airborne early warning aircraft primarily used by the U.S. Navy.

CPI has been producing outer wing panel kits for the E-2D and the C-2A Greyhound since June 2008, and has received orders and advanced funding for the kits totaling about $46.3 million.
